First, the double-layer glass reactor material Description The borosilicate glass has a coefficient of expansion of 3.3, a glass containing sodium oxide (Na2O), boron oxide (B2O3), and silicon dioxide (SiO2) as the basic components. The borosilicate content of the glass component is relatively high, and is boron: 12.5 to 13.5%, and silicon: 78 to 80%. Therefore, this type of glass is called borosilicate glass. It belongs to the Pyrex glass in borosilicate glass. The utility model is characterized in that the thermal expansion coefficient is small, and it is not easy to burst under the sudden change of temperature at high temperature; acid and alkali resistance, water resistance, superior corrosion resistance, good thermal stability, chemical stability and electrical properties, so it has chemical resistance and resistance. It is also known as heat-resistant glass, heat-resistant impact glass, high-temperature resistant glass, and is also a special fireproof glass because of its thermal shock resistance, good mechanical properties, high temperature and high hardness.
The main parameters are as follows:
1. Withstand voltage test: Water pressure test is carried out on pipe fittings such as "glass pipe straight pipe" or "elbow" with a diameter of 2 inches or less. When pressurized to 4kg/cm2, no damage is allowed, in order to retain sufficient Safety factor, the use pressure should not exceed 2kg/cm2.
In order to retain a sufficient safety factor, the reactor or condenser and some thin-walled products should not be used at a pressure of more than 2 kg/cm2. 2. Water resistance: Take a glass powder sample with a particle diameter of 0.3-0.5 mm and boil it with distilled water. The amount of Na2O precipitated was measured at 1 hour, and the amount per gram of the sample was not more than 0.003 mg.
3. Acid resistance: The glass sample was boiled in hydrochloric acid with a content of 20.4% for 3 hours to measure the weight loss, and the calculation was not more than 0.7 mg per 100 cm 2 of surface area.
4. Anti-alkali performance: The glass sample is boiled in a mixed solution of 1 equivalent of NaOH and 1 equivalent of Na2CO3 for three hours, and the weight loss is measured, and the calculation is not more than 90 mg per 100 cm 2 of surface area.
